Under the action of the filter hole 10, the filter material is filtered out from the collecting chamber 6, and the polished metal gum is retained on the polishing seat 7. When the next metal gum needs to be polished, the polishing material flows back to the polishing seat 7 under the lifting action of the spiral lifting mechanism, thereby realizing the recycling of the polishing material and the rapid and automatic removal of the metal gum from the polishing material after polishing.
